Media Converter Switches are super simple to set up and use—just plug and go! Both copper ports are autosensing for speed and duplex, adjusting to the connected device automatically. Plus, the UTP ports feature Auto MDI/MDIX, eliminating the need for crossover cables. Media Converter Switches each have two full sets of LED indicators: one set on the front for viewing convenience when the Media Converter is DIN rail or wallmounted, and one set mounted in the end adjacent to the media ports for easy viewing when units are in a rackmount tray. The Hardened Media Converter are for dusty or dirty environments with temperatures that range between -25 to +60° C.
